Specicationforming part of Letters Patent No. 77,441, dated May 5, 1868.

To all whom it may concern.'

Be it known that I, ANDREW H.

Fig. 2is a perspective view ot' the ring when open.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

I compose my ring of two elliptical parts, A A and B B, which I join bya hinge and pin, C. At D, I extend the partAA in width and thicknessinto a trapezoid, the shorter of the unequal or parallel sides beinguppermost.

vUpon the ends of this trapezoid extension of A A rest thecorrespondingly-shaped ends ot' B B when the ring is closed.

In using this ring I open it and insert the part- A A in the ring orother attachment of the single-tree, Snc., resting said attachmentagainst the extension I). I then insert the part B B in the other oropposite ring or attachment until said ring or attachment is opaycombined in the manner and for the purpose herein set forth.
